I was skeptical about this product working after a few reviewers indicated they had issues with the automatic opener. I have to say that I am pleasantly surprised with how well it works and the amount of trash bags that come with.I like it so much, I am purchasing another one.As this is a review with little short-term statistics, I will keep you posted IF the product doesn't continue to perform as advertised.This item did not come with batteries, which is not a problem. We have many types of battery powered devices in our home. I installed 2 AA batteries and the lid came to life. Of course, I read the instructions after I pushed the buttons to open and close the lid a few times. Our previous trash bins had spring loaded lids which had a propensity of breaking. This can replaced the second such bin after only 3 months of service. We will see how this one performs over the next few weeks and let you know. The lid opens fast, and closes automatically after a few seconds, allowing plenty of time to deposit your waste inside.UPDATE... A month after we had this thing in operation, the lid opens and closes on its own... up, down, up, down... constantly. I changed the batteries and it worked correctly for about a minute. Then the green light would flash... open, then the red light...close. The sensor was nonresponsive, as well as the manual open and close buttons. In my opinion, this product should be thrown in the trash. I would not recommend this to anyone.UPDATE to the UPDATE... I have changed my rating to 5 stars. I read a review that mentioned that the sensor does not like being next to ANYTHING. I have had the can isolated from anything surrounding it, and it has worked perfectly all day. My wife had the can next to the hamper in our bathroom, against the wall, when all of this started. It has worked perfectly all day. I apologize for my previous low ranking. It works great! It just needs to hang out by itself, free from distraction triggers like hampers... and walls, and toilets. I think I am going to use it in the kitchen, on the counter, for simple stuff that I want to throw away. It is working great for me, now that I know that the sensor is more sensitive that I thought.Like everything about it. Exactly as describedI wish it was a little larger but it works great.Nice looking however the motion sections lacks sensitivity!I have to say, I’ve been using this trash can for almost a month now. I wanted to try it out before leaving a review. I have been so happy with everything, and am ready to go order two more. I love the way it looks, how well it works, how well it functions, how well it even holds in the smell of the trash and how easy it is to change out and clean. I have even been asked by friends and family where I ordered it from. Love It!!Really like this trash can, extremely easy to use and the fur babies can’t get in!I like it mostly. Used in bathroom.
